Low Oil Indicator

The "LOW OIL" Indicator is controlled by the Powertrain Control Module (PCM). The PCM will sample the oil level once per Ignition cycle, at power-up only, if criteria has been met indicating that the oil has had sufficient time to drain into the oil pan from the last power-down. Three minutes must elapse after power-down, if Engine coolant temperature is greater than 75°C (167°F) at power-down, for the PCM to sample oil level. If the Engine coolant temperature is less than 75°C (167°F) at power-down, the PCM looks for at least an 11°C (20°F) drop in Engine coolant temperature before sampling oil level at power-up.
